Polyester Film Capacitors

Polyester Film Capacitors for Stable and Reliable Circuit Performance

Polyester film capacitors, also known as PET film capacitors, are widely used in electronic circuits that require stable capacitance, low cost, and dependable long-term performance. Their construction uses a thin metallized polyester dielectric film, which provides excellent electrical insulation, good frequency response, and reliable self-healing characteristics. These properties make them suitable for general-purpose applications including signal coupling, bypassing, decoupling, and low to medium power filtering.
